A package or container includes a side wall, the side wall having an inner surface and an outer surface. At least one of the inner surface or the outer surface of the side wall may be at least partially coated by a layer of a thermally expandable material. The material may be adapted to be expanded to provide thermal insulation.

Examples are disclosed herein that relate to a cooler having a securing structure. One example provides a cooler including a body, a lid movably coupled to the body, a recess formed in the body, a securing structure extending around at least a portion of the recess thereby forming a first lock receptacle, a second lock receptacle formed in the lid and positioned to align over the first lock receptacle when the lid is in a closed position, and a gap located between the securing structure and the lid, the gap being configured to accommodate a locking device when the lid is in the closed position.

Multiple food storage systems are disclosed herein. One food storage system includes a main bowl that defines a first food receiving cavity. A secondary bowl is positioned in the first food receiving cavity and defines a second food receiving cavity. The secondary bowl includes a sidewall containing thermal energy storage material therein. A separate food storage system includes a main lid configured for use with a main bowl that defines a first food receiving cavity. A secondary bowl is positioned at least partially on and/or in the main lid. The secondary bowl includes a sidewall containing thermal energy storage material therein.

A bakeware for preparing food includes a container for receiving ingredients and for separating a resulting food into predetermined portions during a cutting operation. The container has a bottom portion and at least one side wall extending outwardly along a periphery of the bottom portion. The bottom portion and the at least one side wall define an interior surface of the container. The at least one side wall terminates at an upper rim. A cover is disposed on the upper rim and is formed from a low thermal conductivity polymer. The cover includes a portion indicating indicia formed thereon, and each indicium of the portion indicating indicia has a cooperating indicium on an opposing side of the container.
